I found no way to transmit this message in .spam exactly like the one I 
received, because once encoded, it genererated too long lines that may upper 
news server rejects. Unfortunately, I can't choose the same 7-bit 
ISO-2022-JP for sending the message, so the message is full of escape 
sequences that don't cross my news server. If I encode the exact ASCII only 
content, then the ESCAPE characters present in the spam are translated into 
8-bit form using quoted printable, and this generates too long lines (and 
there's no way to recover from that error because lines are not splitted as 
they should, using quoted printable, to bypass this limit, notably in lines 
that don't contain any space).

I see no way to transmit an exact copy of the mailI received to your 
newsserver.
Anyway, there are enough evidence, by the number of links related to the 
same domain, that sukiya-nen.com is spamming, and that its sender is 
accurate (the other links seem to be links to affiliation programs).

So these spams without spaces are a problem, and this will allow spammers in 
chinese, japanese, korean to easily avoiding reporting. After saying that, 
the same technic becomes applicable for other languages, including English 
if they replace all spacesby ideographic spaces, and change to full-width 
ASCII, sent in a ISO-2022 charset.

This looks like a way to prevent reporting of spamvertized sites (so all we 
canreport if one of the millions of open-proxies running in PCs worldwide 
infected by viral spamware, those being the least effective to close after 
abuse reports, because their users are not even aware that their PC is 
harvested this way to relay spam).
